The definitive Lithium Battery Thread

Battery packs are going to have to belong to someone and be leased, then swapped at dedicated charging stations.
They can be super cooled and very fast charged.... or may be the super cooling could be "pipped" into the vehicle for on vehicle charging?
This charge at home or work model can only work for a few percent of town/city workers.
Most people don't have off street parking.... by most I mean nearly all.
In our road the detached houses have parking off street, about 1/3rd of the semi-detached do, but none of the maisonettes... sorry two do, out of say 50.
 
Just resurrecting this thread - same old, same old,

OP
“I’ve just bought a Lithium battery for my ST2, much better cranking power, and so small 👍, highly recommended”

Commenter 1 “you have changed the r/r haven’t you?”

OP “why?”

Commenter 2 “no need too, all my bikes run them, have done for years, they all have built in charging management systems on them now”

Etc etc etc - edited highlights above.

So, Mr @AirCon have you yet reverse engineered the lithium battery @Exige sent you? Can you share your insights?

And, when the r/r begins to break down and starts pumping out 15v and the clever protective circuitry of lithium battery stops the 15v going into the battery cells but only lets in the requisite 12.5–13.5 v or whatever it is, where do the ‘spare’ watts* go?

Edit: I wrote volts originally, I knew it was watts, as a measure of energy, but I used the word volts as some readers (when I link them to this useful thread rather than rewriting everything 100s of times) will only get confused with the sudden switch from too many volts to watts. For this readers, and as per Aircon’s electrickery 101 explanation below, Watts = Volts x Amps

Lets get a quick analogy on the go here.

Water=Electricity
Resistance is how small the pipe / hose is.
Voltage is how much water pressure / heat we have.... here's a diagram
Electricity-101-v2.png


The only place they can do..... Heat.
I'd prefer the term "where do the watts go" rather than volts.
Some people think 4W isn't very much energy, say in a light bulb.... but if I handed you a 4 watt soldering iron and gave you the business end you would quickly become enlightened.

Unless something actually goes open circuit in the battery or it would get insanely hot. I can only assume the the heat is dissipated in the stator and R/R set.

And no.... I'm very bad at projects at home... I've too many of them on the go and get easily distracted by @WAYNE 's special thread....... ..Squirrel.,,,,,,

Volts don't go anywhere.

Coulombs do!

👍 thanks, and I just edited my post to watts and explained why I used the word volts.

Now will you please disassemble that battery, oh and explain in 101 fashion what ‘goes open circuit’ means.

Oh, a broken circuit. So, as the producer of that electricity, ie the r/r, is not a store of it as a battery is, all those watts (or coulombs) have got to go somewhere and I’m struggling to see how, if theyre still being sent down the wires to the battery, just because the ‘smart’ protective circuitry has stopped them going into the lithium battery cells themselves, they’ve got to be accumulating in the protective circuitry and thus would be generating heat albeit from outside the cells rather than within 🤔. But still heat that needs to be dissipated before a combustible event occurs 🤔

Without any load and a faulty generator set, the voltage will continue to climb, as will current until each element in the stator goes open circuit or rotation of the engine stops.

It's more likely to slowly isolate the battery from the circuit rather that shunt the current internally.
 
Depending on who you ask

There are 5 main branches of mathematics, i.e. Algebra, Number Theory, Arithmetic and Geometry. Branching from these oldest branches of math, there are various different specialisations that have sprouted like Probability and Statistics, Topology, Matrix Algebra, Game Theory, Operations Research, amongst others.

Is that a watt or watts? Be careful now because some would have you believe there is only one type of math but yet call it mathematics at the same time, crazy kids 😂

Don't answer then. I don't care.
 
math(ematic)s abbreviated to math's, hence the apostrophe indicating there are missing letters, subsequently dropped as people couldn't be bothered to write the ' hence maths, unless you're 'murcian in which case you can't even be bothered to put the s on the end and wouldn't even know that in the correct form of English such things as ' exist to indicate there are missing letters.

Now, back to Lithium.
